  • Patent number: 6816201
    Abstract: A television system and method for facilitating use of closed caption text or other information that may be included in an extended data service (XDS) system. The system includes a tuner adapted to receive a television signal, the television signal including a video signal and an XDS signal, and a television display for displaying a video image corresponding to the video signal. A data slicer coupled to the tuner extracts the XDS signal from the television signal, and sends the XDS signal out a data port to a peripheral device, such as a text display. The text display may be used to display text information included in the XDS signal, such as closed caption and/or other information included in text fields of the XDS signal. Alternatively, a computer may be coupled to the data port to monitor information, such as URL data, in the XDS signal to access on-line information.
